Description

Technical Field

[0001] The utility model belongs to the technical field of cargo transportation, in particular to a rotary trolley. Background Art

[0002] In traditional cargo transportation, most trolleys lack a rotation feature to ensure stability during transport. This design limits the trolley's flexibility during unloading. If the cargo isn't directly opposite the unloading location when the trolley arrives, operators must move to the opposite side or manually rotate the trolley to adjust the cargo's position. This not only increases the operator's workload, but also creates the risk of the trolley tipping over due to uneven movement and force during rotation.

[0003] In order to solve the above problems, patent CN215244911U "Transport Vehicle" proposes a technical solution, which sets a rotating mechanism on the vehicle body so that the position of the goods can be adjusted by rotating the rotating mechanism when unloading, thereby adapting to the requirements of the unloading position.

[0004] While patent CN215244911U provides a rotation mechanism to improve the cargo unloading process, its position limiting method has certain limitations. The patent only limits the rotation range by cooperating with a rotation angle limiter and a notch on the rotating mechanism's bearing structure. This point-to-point position limiting method requires high control precision and can easily lead to incomplete rotation or excessive rotation, thereby affecting unloading efficiency and safety.

[0005] In order to solve the above problems, designing a rotary trolley is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0006] The purpose of the present invention is to solve the above problems existing in the prior art and to provide a rotary trolley.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] The rotating trolley includes a vehicle body consisting of a base and side walls, and a driving handle is provided on the side wall; a support seat for placing a load-bearing plate is provided on the base, and the load-bearing plate rotates in a plane relative to the vehicle body, and a blocker is provided at the bottom thereof; a positioning mechanism is also provided on the base, and the mounting seat of the positioning mechanism is located on the outside of the load-bearing plate; the positioning mechanism includes at least a positioning pin and a clamp provided on the mounting seat; the positioning pin can optionally pass through the load-bearing plate, and the distal end of the clamp can optionally abut against the side wall of the load-bearing plate; the blocker rotates relative to the mounting seat, and its rotation range is limited by the mounting seat.

[0009] Preferably, the supporting plate is rectangular, and its side walls are formed with side panels extending outward; the side panels are centrally symmetrically arranged, and gaps are formed between the side panels and the side walls of the supporting plate body for easy loading and unloading.

[0010] Preferably, a group of limit blocks are provided at the edge of the upper surface of the supporting plate.

[0011] Preferably, the clamp includes at least a clamp seat connected to the mounting seat, a handle pivotally arranged on the clamp seat, and a clamping part driven by the handle; the handle drives the clamping part to rotate so that the output end of the clamping part abuts against the side wall of the supporting plate, thereby limiting the rotation range of the clamp seat in the length or width direction.

[0012] Preferably, the clamp is also provided with an angle limiting block, which is located between the clamp part and the handle and rotates synchronously with the clamping part until the clamping part abuts against the side wall of the supporting plate, or the end of the angle limiting block contacts the clamp seat.

[0013] Preferably, the angle limiting block limits the handle to drive the clamping part to rotate 90°.

[0014] Preferably, fixed wheels and universal wheels are provided below the base; and the universal wheels and the side walls are located on the same side of the base.

[0015] Preferably, the universal wheel is provided with a brake for controlling the start and stop of the vehicle body.

[0016] The advantages of the technical solution of this utility model are mainly reflected in:

[0017] The present invention aims to provide an improved cargo transport trolley that can maintain transport stability while improving the flexibility and safety of the unloading process through a more precise and reliable rotation mechanism design, reducing the labor intensity of operators and lowering the risk of the trolley tipping over.

[0018] The main body and side panels of the load-bearing plate are arranged in a cross shape and equipped with limit blocks, so that the load-bearing plate can adapt to goods of different sizes. When loading and unloading goods on the load-bearing plate, the loading and unloading device can be located in the gap between the side panels and the main body of the load-bearing plate, which facilitates quick grabbing and loading and unloading, thereby improving loading and unloading efficiency.

[0019] By limiting the position of the carrier plate in the height direction with the positioning pin and then using the clamp to limit the position of the carrier plate in the length or width direction, the clamp can reduce the force on the positioning pin, avoid excessive force on the positioning pin and damage, or excessive rotation of the carrier plate, making the positioning of the positioning pin faster and more effective.

[0020] By setting universal wheels under the base and cooperating with the driving handle, the movement of the vehicle body is made more flexible. At the same time, fixed wheels are provided under the base away from the driving handle to make the vehicle body more stable during movement and reduce its shaking amplitude. The position of the vehicle body is limited by the brakes during loading and unloading to ensure stability during loading and unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model discloses a rotating trolley, such as Figure 1As shown, it includes a vehicle body 1 consisting of a base 11 and a side wall 12. A driving handle 121 is provided on the side wall 12. Fixed wheels 131 and universal wheels 132 are provided below the base 11; and the universal wheels 132 and the side wall 12 are located on the same side of the base 11. Furthermore, a brake 133 for controlling the start and stop of the vehicle body 1 is provided on the universal wheel 132. By arranging the universal wheel 132 below the base 11 and cooperating with the driving handle 121, the movement of the vehicle body 1 is made more flexible. At the same time, a fixed wheel is provided at a position away from the driving handle 121 under the base 11, so that the vehicle body 1 is more stable during movement and its shaking amplitude is reduced; and the brake 133 is used to limit the position of the vehicle body 1 during loading and unloading to ensure stability during loading and unloading.

[0029] like Figures 2 to 3 As shown, the base 11 is provided with a support seat 20 for placing the carrier plate 2. The carrier plate 2 rotates in a plane relative to the vehicle body 1, and a stopper 21 is provided at its bottom. The carrier plate 2 is rectangular, and its side walls are formed with side panels 22 extending outward. The side panels 22 are arranged symmetrically around the center, and a gap is formed between the side panels 22 and the side walls of the carrier plate 2 body to facilitate loading and unloading. Furthermore, a set of limit blocks 23 are provided at the edges of the upper surface of the carrier plate 2.

[0030] like Figure 4 As shown, the main body of the carrying plate 2 and the side plates 22 are distributed in a cross shape, and cooperate with the limit blocks 23, so that the carrying plate 2 can adapt to goods of different sizes; when the goods on the carrying plate 2 are loaded and unloaded, the loading and unloading device can be located in the gap between the side plates 22 and the main body of the carrying plate 2, which is convenient for quick grabbing and loading and unloading, thereby improving loading and unloading efficiency.

[0031] The base 11 is also provided with a positioning mechanism 3, and the mounting seat 30 of the positioning mechanism 3 is located outside the carrying plate 2. Figure 2 As shown, the positioning mechanism 3 includes at least a positioning pin 31 provided on the mounting seat 30. The positioning pin 31 preferably adopts a spring column structure. Since this structure is known in the prior art, it will not be described in detail here. The positioning pin 31 can selectively penetrate the support plate 2 to achieve the positioning of the support plate 2 in the height direction, thereby limiting the rotation range of the support plate 2. Furthermore, during the rotation of the support plate 2, the blocker 21 is driven to rotate synchronously, so that the blocker 21 rotates relative to the mounting seat 30, and its rotation range is limited by the mounting seat 30.

[0032] The positioning mechanism 3 further includes a clamp 32 provided on the mounting seat 30, the distal end of the clamp 32 can selectively abut against the side wall of the carrier plate 21. The number of the clamps 32 can be adjusted according to practical needs and is not limited here. Figure 5 As shown, the clamp 32 comprises at least a clamp base 321 connected to the mounting base 30, a handle 322 pivotally mounted on the clamp base 321, and a clamping portion 323 driven by the handle 322. The handle 322 rotates the clamping portion 323, causing the output end of the clamping portion 323 to abut against the sidewall of the carrier plate 2, thereby limiting the rotation range of the clamp base 321 in the length or width direction. Furthermore, to enhance practicality and comfort, the handle 322 is preferably provided with a rubber sleeve.

[0033] Furthermore, in the present invention, it is preferred that the angle limiting block 324 limits the handle 322 to drive the clamping portion 323 to rotate 90°. Of course, in other embodiments, the rotation angle of the angle limiting block 324 can be adjusted according to the usage, which is not limited here. In the present invention, the position of the carrier plate 2 is limited in the height direction by the positioning pin 31; and the position of the carrier plate 2 is limited in the length or width direction by the clamp 32. The clamp 32 can reduce the force on the positioning pin 31, avoid the positioning pin 31 from being damaged by excessive force, or the carrier plate 2 from rotating excessively. In actual practice, the side wall of the carrier plate 2 can be limited by the clamp 32 first, and then the carrier plate 2 can be accurately positioned by the positioning pin 31 after the carrier plate 2 stops rotating, so that the positioning pin 31 is positioned more quickly and effectively.

[0034] Furthermore, an angle limiting block 324 is provided on the clamp 32, and the angle limiting block 324 is located between the clamp portion 323 and the handle 322, and rotates synchronously with the clamping portion 323 until the clamping portion 323 abuts against the side wall of the supporting plate 2, or the end of the angle limiting block 324 contacts the clamp seat 321; that is, the clamping angle of the clamp 32 is limited by the angle limiting block 324.

[0035] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
